In ration studies, which statistic is the most widely used measure of appraisal level?

• A. Mean
• B. Median
• C. Mode
• D. Standard deviation

Answer: (B)

In ratio studies, the central value you report for appraisal level is best captured by the median. Ratios of appraised to sale prices tend to be skewed and can include outliers, so using the middle value avoids being pulled toward extreme cases. The mean would be distorted by those outliers, giving a misleading sense of a typical appraisal level. The mode is often not informative for continuous ratio data, and standard deviation describes how spread the values are rather than what the typical value is. So the median provides the most reliable summary of appraisal level in this context.
